Description

印刷机中的在线测量及调节 Online measurement and adjustment of the printing press

本发明涉及一种用于在印刷机中的印刷过程期间检测承印物上的光谱测量值、密度测量值或颜色测量值的方法。 Detecting spectral measurement on the substrate of the present invention relates to a process for printing in a printing press during a method of measuring the color value or the measured density values.

在每个印刷过程中力图实现这样的目的:印刷样本尽可能与原始印刷原稿一致。 Trying to achieve this purpose in each of the printing process: printing sample as much as possible consistent with the original print original. 为此需要在印刷企业中通过印刷人员对印刷好的承印物进行费事的品质检验和监测。 To this end the need for cumbersome quality testing and monitoring of the printed substrate in the printing business by printing staff. 根据现有技术,这通过操作人员并且通过使用光学的测量装置进行视觉上的鉴定来实现,所述测量装置或者进行密度测量或者进行光谱测量。 According to the prior art, and this is achieved by using an optical measurement apparatus identified visually by an operator, said measuring means or density measurements or spectroscopic measurements. 为此,在单张纸胶版印刷机中必须将页张从收纸器中取出,该页张通常被放置到一个页张支承台上。 To this end, the sheets must be removed from the delivery device in a sheet-fed offset printing press, this page sheet is typically placed into a sheet support table. 在该台上,用标准化的照明源照亮并且借助于光学测量技术测量或视觉地鉴定页张。 In this stage, with a standardized source of illumination and illuminated by means of optical measurement techniques for measuring or visually identified sheet. 但该过程耗费时间,其中还变得困难的是,当所鉴定的页张还未满足期望时,印刷机在品质检验期间继续印刷并且在此情况下可能产生废页。 However, the process is time-consuming, which also is difficult, when the sheet has not been identified to meet the expectations, the printer continues to print during the quality inspection and in this case may be generated defective products. 因为印刷机在每次中断之后都需要一定数量的页张,直到印刷过程又达到稳定状态,所以也不能通过快速关断印刷机在承印物检查期间避免废页。 Because the sheet printing press after each interruption requires a certain amount until the printing process has reached a steady state, so it can not quickly turn off the printing press to avoid defective products during the inspection of substrates. 此外,为了鉴定印刷页张需要印刷人员,所述印刷人员在品质检验期间不负责其它行为。 In addition, in order to identify the printed sheet to be printed personnel, the personnel during printing quality inspection is not responsible for other acts. 因为在印刷机的调整阶段必须实施尤其是在输墨装置范围内的多种调节可能性,所以,通常产生150与400个页张之间的废页。 Because in the adjustment phase of the printing press to be adjusted more particular embodiment possibilities within the scope of the inking unit, so that defective products typically produce between 150 and 400 sheets. 此外变得更困难的是,印刷过程通常难于再现,因为印刷结果取决于非常多的参数,如油墨、温度、水、纸、印刷速度、橡皮布、印版性质等等。 Further more difficult it is that the printing process is generally difficult to reproduce, since the print result depending on a lot of parameters, such as ink, temperature, water, paper, printing speed, blankets, printing properties and the like. 所有这些参数大多从一个印刷作业到另一个印刷作业以某种形式变化,因此,储存并且对于重复订单完全一样地调用一个印刷作业的调定是不够的,因为例如在此期间空气温度或空气湿度或许已经变化,从而即使对于同一个印刷作业也必须根据变化的环境条件进行重新调定。 Most all of these parameters from one print job to another printing job changes in some form, therefore, call set-stored and a print job is exactly as for repeat orders is not sufficient, since for example during air temperature or air humidity It may have changed, even if the environmental conditions must also be the same for changing a print job readjustment.

因为在卷筒纸胶版印刷机中,已印刷的报纸卷筒纸不可简单地从印刷机中取下,所以在此已经给出了力图光谱或密度测量地检测已印刷的卷筒纸质量的测量系统。 Because the printed paper web can not be easily removed from the printing press in the web offset printing press, the measurements given herein have sought to detect spectral density measurement or the printed web quality system. 由DE 100 23 127 A1公开了一种用来运行用于光学的密度测量的扫描装置的方法。 From the DE 100 23 127 A1 discloses a method for operating a scanning device for optical density measurement of. 在此,在一个卷筒纸胶版印刷机中已印刷的、已离开最后的印刷装置的卷筒纸被转向辊引导,其中,平行于该转向辊安装有一个用于光学的密度测量、颜色测量或光谱测量的扫描装置。 Here, in a web offset printing press it has been printed, the web has left the last printing unit is guided deflecting rollers, wherein, parallel to the steering roller is mounted for measuring the optical density of a color measuring spectral measurement or scanning device. 以此方式方法可测定已印刷的卷筒纸的质量。 In this way the method can determine the quality of the printed web. 在该实施例的说明中表明,在该申请中公开的方法也可用在单张纸形式的承印物上的印刷中。 In the description of this embodiment, it indicates that the method disclosed in this application may also be printed on the sheets in the form of printing material. 但从该申请中不能获知这在实际上如何进行的准确说明,其中,尤其是没有解决这样的问题,即,在单张纸形式的承印物中,完全不可通过如DE 123 127 A1中所述的转向辊引导单张纸形式的承印物,因为单张纸形式的承印物必须至少在一个点上被抓持装置如叼纸牙或印刷装置的印刷间隙抓持。 However, this application can not be known in an accurate description of how this is actually performed, wherein, in particular, does not solve the problem, i.e., in the form of a single sheet of printing material, such as completely non-through in the DE 123 127 A1 the steering roller guides the paper sheets in the form of substrates, because the sheets must be in the form of the substrate is at least one point on the gripping means, such as printing or printing gap gripper means gripping. 出于此原因,在DE123 127 A1中公开的装置不适合在单张纸胶版印刷机中在印刷期间鉴定单张纸形式的承印物的品质。 For this reason, in the apparatus disclosed in DE123 127 A1 unsuitable quality sheet-fed offset printing press in the form of a sheet-fed printing material during the printing identification.

此外,由Ifra Special Report 3.35公开了用于卷筒纸轮转印刷机的在线测量系统,所述在线测量系统以闭环的调节回路工作,即,通过在线测量检测到的用于评价承印卷筒纸印刷质量的测量值直接传送给卷筒纸轮转印刷机的计算机并且在那里被处理。 Further, the Ifra Special Report discloses a system for on-line measurement of 3.35 web rotary printing press, the on-line measurement system working in a closed loop control loop, i.e., detected by the on-line measurement for evaluating printing web printing quality measurements sent directly to the computer web rotary printing press and is processed there. 计算机于是自动地校正可能的偏差并且改变印刷机的调定值。 The computer then automatically correct possible deviations and changes the set-value printer. 但即便是在所述方法中也存在缺点,即仅可在由印刷机的控制装置允许的范围内校正偏差。 However, there are also disadvantages, even in the method, i.e. the deviation can be corrected only to the extent permitted by the control device of the printing press. 因此,尤其是色彩特性描述文件(Farbprofil)的校正不可自动地实现,因为所述校正仅可与来自印前阶段的数据相联系地进行。 Thus, in particular, the correction color profile (Farbprofil) is not automatically achieved because the correction can only be performed in connection with the data from the prepress stage. 此外,在公开的在线测量中,在校正印刷机中的调定值时仅考虑唯一的即刚好当前的印刷订单的数据。 In addition, in-line measurement is disclosed in consideration of only the data that is just the current print order only when it is set in the correction value of the printing press.

因此,本发明的任务在于,提供一种方法,该方法可跨越多个印刷订单自动地校正印刷机中的偏差。 Accordingly, the object of the invention is to provide a method which may span a plurality of offset printing orders automatically corrected printing press.

根据本发明,上述任务根据权利要求1来解决。 According to the present invention, the above-mentioned task solved according to claim 1. 本发明的其它有利构型可由从属权利要求及附图中获知。 Further advantageous configurations of the invention may be claimed in the dependent claims and the accompanying drawings is known. 借助于检测被传送通过印刷机的页张上的测量数据可一直测定印刷机系统的当前状态并且因此可立即通过调节来进行校正,这在现有技术中在单张纸印刷机中是不可能的。 By detecting a current state can be transferred has been measured by the measurement data on the printer system of the printing press and thus the sheets can be corrected immediately by adjusting, which is in the sheet-fed printing press in the prior art can not of. 所述调节可在调整阶段期间、但也可在继续印刷期间进行。 The adjustment may, but may also be performed during the printing is continued during the adjustment phase. 但在继续印刷期间,极其少有地需要校正,因为这里印刷机的状态更稳定。 However, during continue printing, extremely rare land needs to be corrected, because the state where the printing press is more stable. 因此,在继续印刷中不必进行这么多的测量,因此,测量策略可与印刷机的当前的状态相匹配。 Therefore, continue printing does not have to be so many measurements, therefore, measurement strategy can be matched to the current state of the printing press. 这在下面还要继续详细描述。 It also goes on to describe in detail below.

在本发明的一个有利构型中,在印刷机中的印刷过程期间不仅持续地检测所生产的承印物上的光谱测量值、密度测量值或颜色测量值,而且在印刷机的计算机中或在一个分开的计算机中分析处理这些测量值并且至少将那些通过改变对印刷机的调定值不可充分地避免的偏差传送给印前阶段中的控制。 Spectral measurements in an advantageous configuration, the present invention not only is continuously detected during the printing process in a printing press printing material produced, the color density measurements or measurements, but in the computer or in the printing press a separate analysis computer processes the measured values ​​of those deviations and transmits at least the adjustment value by changing the printing press is not sufficient to avoid the control of the prepress stage. 这尤其是在所谓的计算机直接制版技术(CtP)中可相对简单地实现,因为数字的印前阶段设备也具有可从印刷机的计算机接收相应数据的计算机。 This is particularly implemented in a relatively simple manner a so-called computer-to-plate (CtP is), since the digital prepress stage apparatus also has a computer may receive the corresponding data from the computer printer. 以此方式方法,一个闭环的调节回路从加工好的承印物起通过印刷机及印前阶段再返回到印刷机地闭合。 The method of this manner, a closed control loop from the back substrate processed through the press and the press closed to the prepress stage. 由此,可在印前阶段中在制造印版时考虑由印刷机发送的测量值或这些测量值的评价并且由此也可校正在印刷机中单独不能被补偿的偏差。 Thus, consider evaluation measurements transmitted by the printer or the measured values ​​in the manufacture of printing plates and thus also the prepress stage can be corrected in the printer alone can not be compensated for deviation. 可以看出,颜色测量值被理解为色彩空间如Lab色彩空间、RGB色彩空间或其它单义的色彩空间中的值。 As can be seen, the color measurement value is understood as Lab color space color space, the RGB color space or other unambiguous color space. 而且也可跨越多个印刷订单在制造印版时这样考虑测量值:使得跨越多个印刷订单在从印前阶段中的扫描机直到印刷机中的最终产品的整个生产链中进行连续的改善过程。 But also across a plurality of such printing orders considered measurements when producing printing: printing orders that span multiple printers until the entire production chain in the final product in a continuous process improvement from the prepress stage scanner . 以此方式方法可以进行改善过程,不必在费事的过程中检测特殊测试形式。 The method may be performed in this manner to improve the process, do not form during the special test detected the trouble. 因为在如今的数字工作流中很常见地使具有扫描机、印版曝光机、栅格图像处理器(Rasterimageprozessor)的印前阶段设备与印刷机相互联网,所以这些数据即使没有附加的硬件或者说用低的附加费用也可交换。 Because in the digital workflow is common today to have the scanner make, plate exposure machine, raster image processor (Rasterimageprozessor) prepress stage printer device with the Internet, the data even without additional hardware or low additional costs are interchangeable.

在本发明的第一构型中提出,所检测的测量值输入给一个计算机并且该计算机将这些测量值用于在控制印刷机的输墨装置时生成或校正色彩特性描述文件。 In a first configuration of the present invention provides that the detected measurement value input to a computer and the computer used to generate the measured values ​​or corrected color profile control when the inking unit of the printing press. 对于与原稿一致的色彩再现不可缺少的是:将印刷机的色彩特性描述文件与印前阶段的色彩特性描述文件相联系,以便使印刷原稿与印刷最终产品之间的偏差保持尽可能小。 For reproducing the same original color is indispensable: the color characteristics of the printer profile associated with the color profile of the prepress stage, so that the deviation between the printed document and printed the final product as small as possible. 借助于发送给印前阶段设备的、通过在线测量获得的数据可使印刷机的色彩特性描述文件与印前阶段设备的色彩特性描述文件彼此形成联系并且在存在可能的偏差的情况下校正印刷机的色彩特性描述文件。 Case by means of a transmission device to a prepress stage, the data can be obtained by measuring the line color profile color profile prepress stage printer device is formed in contact with each other and there may be deviation correction press the color profiles. 由此,使印刷机的色彩特性描述文件自动地在无印刷人员参与或辅助的情况下被持续地检查并且必要时被适配。 Is continuously checked and adapted when necessary, under a result, the characteristics of the color printer description file is automatically printed without the aid of personnel involved or situations.

在本发明的另一个或可替换的构型中提出,设置有用于测取测量值的传感器并且为了色彩校准以确定的时间间隔借助于校准装置校准这些传感器。 In a further or alternative configuration of the invention it is proposed, provided with a sensor for measuring the measurements taken and in order to determine a color calibration time interval by means of a calibration device calibrating the sensors. 因为在一个在线测量方法中持续地测定测量值,所以必须一定保证:这些测量值可相互比较。 Because the measured values ​​are measured online in a measurement method, it must necessarily guarantee: These measurements may be compared to each other. 因此,为了这种精确的测量,除了在初次投入使用时的一次的标定之外,还需要有规律地校准该系统,以便可以考虑由热或磨损引起的测量值变化、由老化引起的照明源变化或者污染。 Accordingly, in order that accurate measurements, in addition to a calibration when put into use for the first time, but also regularly calibrating the system so that measurements can be considered a change caused by heat or wear, due to aging of the illumination source change or pollution. 为此目的,在印刷机中具有的在线测量装置具有一个校准装置,该校准装置以确定的间隔投入运行。 For this purpose, in the printer having line measuring device having a calibration device, the calibration device to determine the operational intervals. 以此方式方法保证:在线测量系统持续地重新校准并且与运行相关的偏差得以避免。 The method in this manner to ensure: continually re-line measurement system related to the operation and the calibration deviation is avoided.

此外还提出,作为用于校准装置的参考值设有具有所属的颜色测量值的校准面,这些颜色测量值储存在计算机中。 Is also proposed, as a reference value for calibrating means calibrating surface is provided with a color measurement value belongs, the color measurement values ​​stored in the computer. 用于光谱测量、密度测量或颜色测量的、在线测量系统中的测量头为此以确定的时间间隔指向校准面并且被重新校准。 For spectral measurement, measurement or color density measurement, the measuring line measuring system for this head in order to determine the calibration plane and directed intervals recalibrated. 在该测量系统中,在此已知校准面的颜色值,由此可使由测量头测定的值与所储存的颜色值在计算上相比较。 In this measurement system, in the known color values ​​of the calibration surface, thereby allowing the value measured by the measuring head and the color value stored in the calculation of relative comparison. 如果在此情况下出现偏差,则测量头的测量电子电路单元相应地被重新校准,即,这样地进行校正,使得测量值适应于计算机中的所储存的颜色值。 Deviations in this case, the measurement electronics unit is re-calibrated measuring head correspondingly, i.e., corrected in this manner, to adapt the measured value of the color value stored in the computer. 通过该校准也可使被污染的测量头至少在相对长的时间间隔上仍提供可使用的测量结果,而在没有校准的情况下在相对短的时间之后就已会需要净化整个测量装置或更换老化的照明装置。 This also allows calibration by measuring the contaminated head of at least still providing measurements that can be used over a relatively long time intervals, and in the following without calibration had a relatively short time will need to purify or replace the whole measuring apparatus the lighting device aging.

以有利的方式提出,校准面是白色的。 Made in an advantageous manner, the calibration surface is white. 出于颜色测量原因,校准测量应以理想的方式在标准化的白色面上进行,因此,校准面精确地以该色调构造。 For reasons color measurement, calibration measurements should be performed in a standardized manner over a white surface, therefore, to accurately calibrate the hue plane configuration.

此外提出,在印刷滚筒的通道中在印刷滚筒表面的延长中设置有一个或多个校准面。 Also proposed, provided with one or more calibration surfaces extended in the printing cylinder surface of the print cylinder channel. 因为在32个墨区的情况下在线测量系统在承印物的宽度上分布地具有多个测量头、优选八个测量头,所以必须借助于校准面调节及检查全部测量头。 32 because in the ink zone line measurement system having a plurality of measuring heads distributed over the width of the printing material, preferably eight measuring head must be adjusted by means of calibration and inspection of all surface measuring head. 但因为测量头的侧向的可运动性受到限制,所以不可能使全部测量头移动到安置在侧面的校准面。 However, because the measured lateral motion of the head can be restricted, so that it is impossible to move all of the measuring head is disposed on the side of the calibration plane. 此外重要的是,校准面与测量头之间的距离精确地等于测量头表面与承印物表面之间的距离。 Also important is that the distance between the calibration surface and the measurement head is exactly equal to the measured distance between the head surface and the substrate surface. 为了可将用于全部测量头的校准面安置在承印物的整个宽度上,将这些测量头设置在一个印刷滚筒的通道中在该印刷滚筒表面的延长中。 May be used to calibrate the entire surface of the measuring head is disposed over the entire width of the substrate, these measuring head disposed in the channel in a printing cylinder of the printing cylinder extended surface. 由此,校准面相对于测量头与承印物表面相对于测量头精确地具有相同的距离并且在印刷过程中不造成妨碍。 Thus, the calibration for the measuring head and the surface of the substrate surface relative to the measuring head has exactly the same distance and without hindrance in the printing process.

在本发明的一个可替换的实施形式中提出,至少一个校准面在侧面设置在印刷滚筒表面之外地位于侧壁与印刷滚筒之间。 In an alternative embodiment of the present invention, it is proposed that at least one calibration surface arranged laterally outside the side wall of the printing cylinder between the printing cylinder surface. 位于印刷通道中的校准面具有很大的缺点,即这些校准面在印刷过程期间被污染。 In the adjustment path of the printing surface with great disadvantage that these calibration surface is contaminated during the printing process. 而如果校准面相反位于印刷滚筒表面之外,例如位于侧壁的区域中,则该校准面在那里很少遭受污染。 If the calibration surface opposite to the surface located outside the printing cylinder, for example, the region of side walls, the plane where the calibration little contamination. 由此避免了校准面的频繁的清洗过程。 Thereby avoiding frequent cleaning of the surface during calibration.

在本发明的一个特别有利的构型中提出,这些传感器是测量头,并且,通过一个测量头的校准测定的校准值借助于计算机换算成用于其它测量头的校准值。 In a particularly advantageous refinement of the invention it is proposed, these sensors are measuring head, and the calibration values ​​determined by calibrating the measuring head by means of a computer into calibration values ​​for the other in terms of the measuring head. 该方法也被称为转移校准,因为在此不将全部测量头在自己的校准面上校准,而是一个设置在滚筒表面之外、例如设置在侧壁与印刷滚筒之间的校准面就够了。 This approach is also referred to as calibration transfer, since in this measuring head is not all in their calibration calibration surface, but a surface disposed outside of the drum, such as a calibration surface disposed between the side wall of the printing cylinder is enough a. 但该校准面仅可由检测承印物边缘的测量头中的一个测量,因为仅仅这些测量头可在侧向移动超过印刷滚筒的边界。 However, the calibration of a measuring head face printing material only by the edges, since only the boundaries of these measuring heads printing cylinder can move laterally over. 其它测量头通过转移校准来标定,其方式是,整个测量杆被进一步移过一个移动行程,该移动行程等于测量头相互间的距离。 Other measuring head to calibrate a calibration transfer by such a manner that the entire measuring rod is further moved through a stroke of movement, the stroke of movement equal to the distance between the measuring head from each other. 由此,仅仅在边缘区域中的一个唯一的测量头必须在校准面上被校准,而在下一步骤中测量杆移过测量头的间距,由此,该被校准的第一测量头可检测第二测量头的区域。 Thus, only a single measuring head in the edge region of the surface must be calibrated in the calibration, the measuring head moves past the measuring rod spacing in the next step, whereby the calibrated first measurement head may Detection second area of ​​the measuring head. 类似地,这也适用于其它测量头,即每个测量头现在检测位于其旁边的测量头的测量区。 Similarly, this also applies to other measuring head, i.e., each measuring head is now located in the detection of the measurement zone next to the measuring head. 在该校准测量期间,这些测量头或者对准白色的承印物,或者对准彩色印刷的承印物。 During this calibration measurement, the measuring head or the substrate at a white or color printing the alignment substrate. 但这对于校准测量过程不起作用。 But it does not work for the calibration measurement process. 如果例如通过该校准面标定的第一测量头旁边的第二测量头正好已检测了一个确定的蓝色色调,则该蓝色色调在下一步骤中由已被标定的第一测量头检测。 If, for example, by the calibration measurement of the second surface of the first calibration measurement head just beside the head has been detected a certain blue tint, the blue tint detected by the first measuring head has been calibrated in the next step. 现在使第一测量头与第二测量头的测量值相互比较并且必要时校正第二测量头的值。 Now that the first measurement head to each other compared with the measured values ​​of the measuring head and the second correction value of the second measuring head when necessary. 由此,向第二测量头上的转移校准结束并且第二测量头的必要时被校正的测量值可与第三测量头的测量值相比较。 Thus, the second end of the measurement head transfer calibration and the measured value may be compared with the corrected measured value of the third measurement head, if necessary, a second measuring head. 这以重复的方法对于所有其它测量头都一样进行,由此,仅一个唯一的测量头必须借助于校准面来校准,而所有其它测量头在一个步骤中通过计算上的比较来校准。 This method of repeating the same for all other measuring head, whereby, only a single probe must be calibrated by means of calibration surfaces, while all other measurements calibrated by comparing the first calculated in one step.

此外提出,至少一个校准面可借助于一个盖封闭。 Also proposed, at least one calibration surface can be closed by means of a cover. 借助于这样一个盖可以可靠地保护所述校准面以免在印刷过程期间被污染。 By means of such a cover can be reliably protected to prevent contamination of the calibration surface during the printing process. 该盖仅当一个校准过程必须进行时才打开。 The cover opens only when a calibration procedure must be performed. 由此取消了否则总是重复地必需的校准面清洁。 Thereby eliminating the calibration surfaces are clean and otherwise always repeatedly required.

已证明有利的是,校准借助于一个外部的测量装置进行。 It has proven advantageous that the calibration means of an external measuring device. 因为所有安置在机器中的部件易受污染且易受干扰,所以转移校准也可借助于一个外部的测量装置进行。 Because all the components disposed in the machine vulnerable to pollution and susceptible to interference, it may also be transferred to an external calibration device by means of a measurement. 为此,在操作台上有一个固定地装入的测量装置或一个手动测量装置,该测量装置或该手动测量装置具有一个自己的装入的校准面、以均匀的间隔在该面上校准,并且用该测量装置或该手动测量装置测量刚刚印刷的承印物。 To this end, the operating table there is fixedly mounted a measuring device or a manual measuring device, the measuring device or measuring means of the manual calibration plane having its own loaded, at regular intervals on the surface of the calibration, and means for measuring the printed substrate just measured by the measuring device or the manual. 因为该承印物先前被在线测量装置及其测量头测量并且已从印刷机中取出,所以,之后用手动测量装置测定的值可直接传送给测量杆中的测量电子电路单元,并且由此进行相应的校准。 Since the previous line of the substrate is measured and the measuring device and the measuring head removed from the printer, so that, after the value measured by the measuring device may be manually sent directly to the measuring rod in the measurement electronic circuit unit, and thus the corresponding calibration. 当然,承印物也可首先在未被印刷的状态中、即作为纸的白度用手动测量装置然后在印刷机中借助于在线测量装置的测量头测量。 Of course, the first substrate may be unprinted state, i.e., as the whiteness of the paper by hand in the printing press and then measuring apparatus by means of measuring device for measuring the head line. 因此也可用一个外部的测量装置进行转移校准。 Thus also it is an external measuring device calibration transfer. 特别有利的是,校准在不被印刷的区域中直接在叼纸牙后进行,因为在此页张被理想地引导并且为此总是存在纸的白度。 It is particularly advantageous, after calibration gripper directly in the unprinted areas, since this is guided over the sheet and there is always the whiteness of the paper for this. 所述边缘区域通常具有6~12mm的未被印刷的面并且对于测量完全足够。 Said edge having a surface area generally unprinted 6 ~ 12mm and is fully adequate for the measurement.

但该外部的手动测量装置也可还被用于其它目的。 However, the external device may also be a manual measurement is further used for other purposes. 页张在机器中出于多种原因借助于一个偏振滤光器测量,即,所有测量值被偏振地检测。 Sheets for various reasons measured by means of a polarizing filter, i.e., in the machine, all measured values ​​detected by polarization. 但印刷机的调节用未偏振化的值工作,因为来自印前阶段的信息仅仅未偏振地存在,即,所检测的测量值必须转换成未偏振的值。 However, adjustment of the printing press with the value of unpolarized work, since only information from the prepress stage unpolarized exist, i.e., the detected measurement values ​​must be converted into unpolarized value. 为此,偏振的与不被偏振的值之间的计算上的关系必须储存在印刷机中。 For this purpose, the polarization is not calculated relationship between the polarization values ​​must be stored in the printing press. 该关系可借助于不偏振地进行测量的手动测量装置来建立。 This relationship can be performed manually without polarization measuring device for measuring by means of a established. 因此,页张被印刷机中的在线测量装置偏振地测量一次并且在机器之外借助于手动测量装置不偏振及偏振地测量一次。 Thus, the sheets are press-line measurement of the polarization measuring device and by means of a manual measurement apparatus does not measure the polarization and the polarization time outside of the machine. 如果该测量跨越多个页张进行,则可看出偏振的与不偏振的测量值之间的关系。 If the measurement performed across a plurality of sheets, you can see the relationship between the polarized and non-polarized measurements. 该关系然后作为校正函数存储在印刷机的计算机中,由此,这些值随时都可相互转换。 This relationship is then stored in the computer as a correction function of the printing press, whereby, at any time these conversion values.

在本发明的另一个构型中提出,对于每个测量头在计算机中存储一些确定的颜色值,这些颜色值的相互关系储存在计算机中并且在所储存的测量值关系变化时输出一个信号。 In a further feature of the present invention, it is proposed that, for each measuring head certain color values ​​stored in some of the computer, the relationship between the color values ​​stored in the computer and outputs a signal when the change in the relationship between the measured value stored. 借助于这样一个装置识别在线测量系统的污染。 With such a device identification pollution line measurement system. 每个分光计例如在输出时具有一个白测量值作为初始化参数。 Each spectrometer having a white e.g. as measured at the output as the initialization parameter. 属于对应测量头的白测量值以它们的相互关系对于所有测量头被储存。 White measurement values ​​belonging to the corresponding measuring head with their mutual relations are stored for all measuring heads. 在印刷过程期间则持续地进行纸的白度测量并且将在此测定的测量值关系与储存在测量电子电路单元中的值相比较。 Is continuously performed measurement of whiteness of the paper during the printing process and the relationship between the measured values ​​in this assay and measurement values ​​are stored in the electronic circuit unit is compared. 一旦这些关系变化,其中可调节一定的容差范围,则这作为用于污染的信号被评价。 Once these relationships change, wherein the adjustable certain tolerance range, which is evaluated as a signal for contamination. 在此情况下向操作人员显示声学的或视觉的信号,此后应进行测量头的清洁。 Acoustic or a visual display signal to the operator in this case, after the measurement head should be cleaned.

此外提出,一个第一测量头检测其自己的墨区且检测位于该第一测量头旁边的第二测量头的墨区,第二测量头也检测其自己的墨区及第一测量头的墨区,并且将所检测的测量值相互比较。 Also proposed, a first measuring probe with its own ink zone and the ink zone of the second detector is located next to the measuring head of the first measuring head, a second measuring head also detects its own ink zone and the ink first measuring head region, and the detected measured values ​​with each other. 以此方式方法可实现印刷机中杆状的在线测量装置的测量模块的各个测量头之间的交叉比较。 Cross comparison between the respective measuring head line measurement module measuring device of the method may be implemented in this printer a rod. 首先,全部测量头同时测量承印物上的一个墨区,然后,整个测量杆这种程度地侧向移动,使得现在每个测量头可检测其邻居的测量部位。 First, a simultaneous measurement of all the measuring heads on the printing region of the ink composition, and then, this lateral movement of the entire measuring beam extent, so that each measuring head can now detect the measurement site of its neighbors. 在正确地进行的校准中不允许这些测量值不同或者仅允许在非常窄的容差极限内不同。 These measurements allowed the different calibration performed correctly or allow different only within a very narrow tolerance limits. 但如果这些测量值显示出偏差,则也由此推断出测量头的光学装置上有污染。 However, if these measurements show a deviation, it is also deduce therefrom the measurement of contamination on the optical head device.

揭示测量系统上的污染的另一个可能性这样得到:在一个测量头的至少一个墨区上进行一个亮/暗-边上的测量,其中,该测量头以均匀的步长从该亮/暗-边的另一侧起越过亮/暗-边运动直到亮/暗-边的这一侧,并且将在此检测的强度测量值与该测量头的已知结构相比较。 Another possibility disclosed contamination measuring system thus obtained: for a light / dark on the at least one ink zone a measuring head - side of the measuring, wherein the measuring head from a uniform step size of the light / dark - from the other side edge over the light / dark - side motion until the bright / dark - this side edge, and the measured value of the intensity detected here compared with known structure of the measuring head. 这样一个亮/暗-边例如是从纸的白度过渡到油墨区域的过渡部分。 Such a light / dark - for example, the transition from the edge of the paper to the white ink transition zone. 该测量区域现在由一个测量头如下地走过。 The measurement region is now passed by the measuring head follows a. 首先该测量头在亮/暗-边的显示纸的白度的侧上进行测量。 First, the measuring head in the light / dark - side of the display side measuring whiteness of the paper. 接着,测量杆例如以10步运动跨越亮/暗-边的测量区的宽度,其中进行10次测量。 Next, the measuring beam moving across the step 10 for example light / dark - a edge width measurement zone, where 10 measurements. 这就是说,最后的测量完整地在测量区的油墨区域中进行。 That is, the last measured completely in the ink region of the measurement zone. 在分析处理这些测量时,描绘出在位置偏移上的相应测量的强度,其中,最后测量的白色值与所测量的第一颜色值之间的距离在精确的光学影像中必须等于测量头的分光计的测量区域的公知结构宽度。 When analysis of these measurements, the intensity of the corresponding drawing on the measured positional displacement, wherein the distance between the last measured value and the white color of the first measured value must be equal to the accurate optical image measuring head well-known structures width of the measurement region of the spectrometer. 该比较借助于测量电子电路单元和分光计的测量区域的结构的在那里存储的值进行。 The comparison means of the measured values ​​stored in the configuration where an electronic circuit unit and the spectrometer measurement region is performed. 如果在此得到偏差,则这也是用于污染的指示。 If this deviation obtained, which is used to indicate the contamination.

此外提出,设有一个照明装置,在真正的测量之前通过测量头进行暗测量并且从在照明装置接通时进行的颜色测量减去在此检测的测量值。 Also proposed, provided with a lighting device, before the actual measurement by the measuring head and measuring a dark color measurements made from the lighting device is switched on by subtracting this measured value detected. 为了可扫描承印物的表面,该表面必须用测量头附近的照明装置照亮。 In order to be scanned surface of the substrate, the surface to be illuminated by the lighting device near the measuring head. 但因为在承印物与测量杆之间存在多个厘米的距离,所以在承印物与测量头/照明装置之间的区域中也可射入外部光。 However, since the distance between the plurality cm medium and the presence in the measuring beam, so that in a region between the medium and the measuring head / illumination device may be incident on the external light. 这使得测量结果失真并且必须相应地补偿。 This makes the distortion of the measurement results and must be compensated accordingly. 存在这样一个可能性:进行暗测量,即,照明装置首先关断,在关断的照明装置情况下进行测量。 Such a possibility that: a dark measurement, i.e., the lighting device is turned off first, the measurement apparatus in the case where the lighting is turned off. 然后,接通照明并且在接通的照明装置情况下进行测量。 Then, the lighting is turned on and the measurement device in the case where the illumination is turned on. 顺序在此不起作用,因为为了校正仅须从伴随着接通的照明所检测的测量值中减去在暗测量时所检测的测量值。 The order does not work, because only needs to be subtracted in order to correct the measured values ​​measured during the dark along with the detected illumination is turned from the detected measured values. 干扰光或外部光源例如是机器中的缝隙,印刷厂的天花板照明或日光可穿过这些缝隙射入,但也可以是机器本身中的光源、例如UV/IR干燥器或其它传感器,这些传感器用光工作并且它们的光会干扰测量过程。 Or an external disturbance light source, for example, slot machines, printing may be ceiling illumination or sunlight incident through the slits, but the machine itself may be a light source, e.g. UV / IR dryer or other sensors that use light work and interfere with their optical measurement process. 借助于一个小的变化也可补偿周期地工作的外部光源。 Also by means of a small change in external light source operable periodically to compensate. 因此,首先进行暗测量,由此第一次检测外部光影响。 Therefore, first, a dark measurement, whereby the first detecting external light. 然后进行亮测量并且接着又一个暗测量,在该暗测量中又仅检测外部光影响。 Then followed a bright and dark measured measurement, but only the external light detected in the measurement of the dark. 如果外部光源变化,则这两个暗测量的测量值彼此不同并且计算机可通过这两个测量值的比较识别:是否外部光在亮测量期间已增强或减弱,因为它可使之前的测量值与之后的测量值相比较。 If the external light source changes, the two measured values ​​differ from each other and the measured dark computer identified by comparing the two measured values: whether outside light has been increased or decreased during the measurement of the light, because it allows the measurement value before the after comparing the measured values. 即可测定外部光变化的梯度,由此,外部光影响也可从亮测量中即使在尤其是周期的外部光变化的情况下可靠地计算出来。 Determination of the external light to change the gradient, thus, external light can be reliably calculated from the measurement light, especially even in the case of the external light variation period.

在外部光射入时用于校正的另一个可能性在于,与第一测量头的颜色测量同时地借助于第二测量头检测承印物的白背景上的测量值并且将由此测定的白度参考值用于校正用第一测量头测定的颜色测量值。 Another possibility for correction when external light is incident in that, by means of a color measuring head simultaneously measuring a first measured value on a white background of the second substrate measuring probe and the reference whiteness thus determined values ​​for correcting color measurement values ​​measured by the first measuring head. 第二测量头必须为此在空间上与第一测量头分开地安置,该第一测量头总是必须进行在纸的白度上的测量。 The second probe must be separately arranged for this purpose in the first measurement head space, the first measuring head must always be measured on the whiteness of the paper. 它例如可以是承印物的边缘区域。 It may be, for example, an edge region of the substrate. 用第二测量头测定的白度参考值被考虑到颜色值或密度值的计算中并且外部光的影响由此被补偿。 Whiteness head with a reference value measured in the second measurement is calculated taking into account the density values ​​or color values ​​and the influence of outside light is thereby compensated.

还存在另一个用于外部光补偿的可能性,即在通过一个或多个测量头检测承印物上的测量值期间将可能存在的光源关断、遮蔽或者减小亮度到一个非临界的值。 There is also another possibility for compensation of external light, i.e. the light source is turned off is detected may be present during the measurement on the substrate by one or more measuring heads, shading or reduce the brightness to a non-critical value. 在此情况下,测量头的测量电子电路单元与印刷机的计算机联网,由此在测量过程期间关断印刷机中的光源。 In this case, the electronic measuring circuit unit of the printing press measuring head computer networking, whereby the measuring light source is turned off during the printing press process. 因此,例如通过UV干燥器在测量期间引起的外部光影响被这样避免:干燥器在测量期间被短时地关断,之后又接通。 Thus, for example, so to avoid influence by external light UV dryer during the measurement due to: the dryer is briefly switched off during the measurement, and then turned. 另一个可能性在于,将外部光源遮蔽,其方式是,将一个遮挡器(遮光器)安置在外部光源前面。 Another possibility is that the external light shielding a manner, a shutter (shutter) disposed in front of the external light. 该遮挡器遮掩着外部光源,直到测量过程被进行。 The shutter cover with an external light source, until the measurement process is performed. 也可有目的地虑除外部光源的处于测量装置的光谱范围中的光谱值,其方式是安置一个滤光器,该滤光器虑除出外部光源的光谱。 Destination may also be considered with the exception of the light source spectral values ​​in the spectral range of the measuring device, which is disposed a filter mode, the spectral filter into account in addition to an external light source. 一个类似的效应通过计算上的内插法实现。 To achieve a similar effect on the interpolation is calculated by. 因为外部光源的光谱是已知的,所以不使用与测量光谱相应的光谱值,取而代之的是借助于相邻值在外部光源的光谱上内插不可用的值。 Since external light source spectrum is known, the measured spectrum is not used and the corresponding spectral values, instead of by means of interpolation of neighboring values ​​are not available in the spectrum of the external light source. 由此可计算出测量光谱中的通过外部光源引起的峰值。 Whereby the peak spectrum by an external light source can be calculated due to measurement.

为了补偿外部光还给出了下面的可能性,即,借助于至少一个检测光源的可能的波动的传感器或借助于波动的光源的控制信号使通过测量头进行的测量值检测与光源的波动在时间上协调。 To compensate for the external light but also gives the possibility below, i.e., by means of the at least one control signal sensor may detect light fluctuations of the light source or by means of the ripple fluctuating measured value detection is performed by the light source in the measuring head on coordinated Universal time. 在此情况下也必须有关于外部光源的时间特性的信息,即,或者这些值必须储存在一个计算机中,或者外部光源通过传感器将这些信息在线地提供给该计算机。 In this case, the time must also have information about the characteristics of the external light source, i.e., the values ​​or must be stored in a computer, or an external light sensor the information provided to the online computer. 在此情况下,由计算机使这些测量这样协调,使得总是当外部光源被关断或具有一个最小值时才测量。 In this case, by a computer to make these measurements coordinated so that always a minimum value when the measure only the external light source is turned off or has.

另外提出,多个测量头以等距的距离跨越承印物的宽度地分布并且同时检测墨区。 Also proposed, a plurality of equidistant distance measuring head across the width of the substrate and simultaneously detect the ink distribution zone. 在单张纸印刷机中大规格(102cm的页张宽度)情况下,在整个承印物宽度上延伸着32个墨区,由此在6种印刷颜色时得到192个测量块,这些测量块可被测量电子电路单元和测量头检测。 In the sheet-fed printing press in large size (102cm width of the sheet), the substrate extends over the entire width of the ink zone 32, thereby obtaining a block 192 measuring 6 printed colors, these blocks can be measured electronic circuit unit is measured, and measuring probe. 在一个唯一的光谱测量头上,在此需要在至少192个页张上的多个测量循环,这对于良好的调节并非足够。 In a unique spectral measuring head, in need thereof a plurality of measurement cycles on the sheets at least 192, this is not sufficient for good regulation. 出于这个原因,需要多个测量头,这些测量头能够并行地且同时地测量。 For this reason, a plurality of measuring heads, the measuring head can be measured simultaneously and in parallel. 因为在每个测量过程之后使这些测量头在时间上错位一个墨区,所以尤其是8、16或32个测量头理想地适用于并行的测量。 Because these measuring head after each measurement one ink zone offset in time, so in particular the measuring head 8, 16 or 32 is ideally suited for parallel measurements. 据此,在32个测量头和32个墨区以及6种所印刷的颜色的情况下,必须在6张印刷的页张上进行6个测量过程。 Accordingly, in a case where the measuring head 32 and an ink 32 of the printed area and six kinds of color, the process must be performed six measurements on six printing sheet. 在这6个测量步骤之后,现在必要时可进行印刷机调定值的再调整,其方式是,所校正的值用印刷机上的新的墨区调定值来调节。 After six measurement steps, if necessary, can now be re-adjusted value of the printing press in such a manner that the corrected value with the new ink zone on a printing press set-value is adjusted. 除了所述测量策略之外,这些测量头也可这样地移动,使得首先跨越多张页张总是检测相同的颜色,由此,它可被良好地调节并且只有这时测量头才定位到下一种颜色,该下一种颜色则也被调整。 In addition to the measurement method, measurement heads may be movable in such a way that a plurality of first sheet across the same color is always detected, whereby it can be well adjusted, and only then was positioned on the lower measuring head one color, the lower the color is also adjusted. 因为可使用不同的测量策略,所以,测量装置必须将具有时间戳(Zeitstempel)及位置标记的测量值储存在印刷机的计算机中,由此随时可建立正确的参考,以便可使实际上可比较的测量值正确地相互比较。 Because different measurement methods may be used, so that the measuring device must be measured with a timestamp value (Zeitstempel) and the position of the mark stored in the computer of the printing press, whereby the correct reference may be established at any time, so that in fact can be compared comparing each measured value accurately. 然后测量策略不再起作用并且测量值随时可正确地配置。 Then measurement strategy no longer works and the measured values ​​can always be properly configured.

此外,在本发明的一个构型中提出,在起始印刷之后的印刷工作期间,这些测量头这样地定位,使得这些测量头同时检测多个颜色。 Further, in a configuration proposed in the present invention, during the printing operation after the initial printing, the measuring head is positioned so that the measuring head simultaneously detect a plurality of colors. 因为通过频繁测量使得具有测量头的测量杆的机械装置及驱动电动机强地负荷,所以,所谓的节省运行提高了寿命。 Since such mechanical means through frequent measurement and the measuring head a drive motor having a load measuring rod strongly, so-called improved life saving operation. 但因为在起始印刷阶段中这些值仍与过程相关地强地变化,所以在那里必须进行连续频繁的测量,而在正式印刷阶段中可选择另一个处理方式,因为在正式印刷阶段中颜色值在时间上看保持几乎恒定,由此可使测量头定位在一些混合块上。 However, because these values ​​are still strongly vary with the process in relation to the initial printing stage, there must be continuous so frequent measurements, and the processing mode select another stage in continuous printing, because the color values ​​in continuous printing stage at the time point of view remains almost constant, whereby the measuring head can be positioned some mixing block. 一旦识别到一个过大的容许偏差,则测量杆又开始以其在起始印刷阶段中那样的频繁的测量,这些测量检测所有色块及所有区。 Once an excessively large tolerance is identified, the measuring rod began its frequent measurements as in the initial printing stage, these patches and all measurements of all detected regions. 由此可测量出偏差的原因并且可相应地激活印刷机的调节。 Cause and thereby measure the deviation may be adjusted accordingly activation press.

测量装置也可根据所检测的测量值改变其测量策略。 Measuring device may also change its value according to the detected measuring strategy measured. 因此,显示很低噪声的色块不像具有强噪声的色块那样经常地被测量。 Accordingly, the display having low noise color patches not as strong noise is often measured. 即每种颜色用不同的测量策略来检测,以便更经常地测量噪声更强的颜色。 I.e., each color used to detect different measurement strategies in order to measure more often stronger color noise. 如果这些颜色(Farben)中的噪声消退,则也改变测量策略,以便降低频繁的测量。 If these colors (Farben) noise subsided, the measurement method is also changed so as to reduce frequent measurements. 测量策略也可与印刷图像及印刷机本身的调定值相关地实现。 Measurement strategies can also be implemented in association with the tone value and press the printed image itself. 因为印刷图像的数据可从印前阶段传输给计算机,所以测量系统可计算出一个相应的测量策略,因为印刷图像中的关键的颜色区域事先在其位置及色调上是已知的。 Since the print image data may be transmitted to the computer from the prepress stage, the measurement system can calculate a corresponding measurement strategy, because the critical area of ​​the printed color image in advance on the position and the color tone are known.

在本发明的另一个构型中提出,计算机存储施加在承印物上的印刷质量控制条的位置坐标。 In a further feature of the present invention that the position coordinates of print control strip on the printing material is applied to computer storage. 墨区上的测量在印刷机中通常在印刷质量控制条的区域中进行。 Measuring the inking zone is generally carried out in the print control strip in the area quality in the printing press. 为了可以可靠地进行这些测量,印刷质量控制条在承印物上的位置对于在线测量系统的测量杆必须是已知的。 For these measurements can be reliably performed, the position of the print control strip on the printing material measuring rod for online measurement system must be known. 一种可能性在于:印刷工人手动地测量出印刷质量控制条在印版上的位置并且将印刷质量控制条的位置坐标输入到机器控制装置的计算机中。 One possibility is that: the pressman to manually measure the position of the print control strip on the printing plate and the position coordinates of print control strips is input to the machine control computer apparatus. 此外,位置坐标也可从联网的工作流系统中的印前阶段设备传输给印刷机的计算机并且在那里被使用。 Further, the position coordinates of the stage device can transmit the prepress workflow system network from the printer to the computer and is used there. 但在这两种可能性中存在危险,即在印版夹紧在印刷机中的情况下或通过套准调节,印刷质量控制条在印刷页张上的位置相对于测量头被改变。 But the risk exists in both possibilities, i.e. in the case of the clamping plate in the printing press or by the register, the position of the print control strip on the printed sheet relative to the measuring head is changed. 不过用预给定的粗位置可限定用于精确的位置确定的搜索区域,由此对于自动的位置识别系统简化了工作。 However, with a given pre-defined for accurate coarse position location determination of the search area, whereby the position of the automatic identification system for simplifying the work.

此外提出,设置有一个用于测定印刷质量控制条在承印物上的位置的传感器。 Also proposed, there is provided a sensor for measuring the position of the print control strip on the printing material used. 借助于一个两维的传感器,例如借助于一个CCD图像转换器,可测定印刷质量控制条的位置。 By means of a two-dimensional sensor, for example by means of a CCD image converter can be determined the position of the print control strip. 印刷质量控制条的图案储存在机器控制装置中,该图案与通过CCD摄像机检测的那些图像中的图像相比较。 Print control strip patterns stored in the machine control apparatus, the pattern is compared with the image that the image of the CCD camera detection. 一旦该摄像机确定相同性,则计算机可计算印刷质量控制条相对于测量杆的位置并且将一个相应的开始信号发送给该测量杆,以便刚好当印刷质量控制条位于测量头下面时开始测量。 Once the camera determines the identity, then the computer can calculate the print control strip relative to the measuring rod and transmits a start signal corresponding to the measuring beam, so that measurement starts just when the print control strip positioned beneath the measuring head. 而且,如果在印刷质量控制条前面存在一个识别段、例如一个条形码,使用一个一维的传感器也适用于印刷质量控制条的位置识别。 Further, if the presence of a bar in front of the control section identifying the print quality, such as a barcode, to use a one-dimensional position recognition sensor is also applicable to the print control strip. 一旦该条形码被一个棒码阅读器识别,对于该系统就已知:现在以一个确定的时间间隔跟随印刷质量控制条。 Once the barcode identification is a bar code reader, it is known to the system: In order to determine a time interval following the print control strip. 由此可及时地触发测量过程。 Thus may trigger the measurement process in a timely manner. 位置识别仅在印刷过程开始时才需要,因为在此还可预计到更大的位置偏差。 Location identification process begins only when printing requires only because this is also expected to be greater position deviation. 在正式印刷阶段中,标记的位置是稳定的,由此,在此识别段仅须以大的时间间隔被扫描以便检查。 In continuous printing stage, the marked position is stable, whereby, in this section only has to be identified with a large time interval is scanned to check.

本发明的一个特别有利的构型的特征在于,通过测量头测定的测量值在每次测量之后都经历一个合理性测试。 A particularly advantageous configuration of the present invention is characterized in that the measured values ​​measured by the measuring head are subjected to a reasonableness test after each measurement. 在具有闭环的调节回路的在线测量系统中特别重要的是,自动地识别并且剔除有误差的测量值,因为否则墨区控制装置调节出错误的颜色值并且产生不必要的废页,而关于此不通知给操作人员。 Of particular importance in an online measuring system has a closed control loop are automatically identified and eliminated with a measurement error, because otherwise the ink zone control means for adjusting an error value, and a color page unnecessary waste, but on this without notice to the operator. 出于这个原因,具有闭环的调节回路的在线测量系统应使测量值经历一个合理性测试,以便可剔除不合理的测量值。 For this reason, on-line measuring system has a closed-loop control loop is such that the measured value to a reasonableness test, in order to be eliminated unreasonable measurements. 这样的校验例如通过印刷质量控制条的所储存的原稿与测量杆的在每个测量过程中所检测的值之间的关联性来实现。 Such check, for example, the correlation between values ​​of the print control strip with the document stored in each of the measuring beam detected during the measurement is achieved. 由此保证:测量杆总是移动到正确的测量块上。 This ensures that: the measuring beam is always moved to the correct measuring block. 正确的印刷质量控制条类型的选择可通过进一步的算法检验,其方式是,传感器检测印刷质量控制条内的编码块并且检验在其中被编码的数据。 Appropriate print control strip type selection algorithm by further testing, in such a manner that the coded blocks in a strip sensor for detecting the printing quality control and inspection in which the coded data. 此外,在每个测量过程中不仅在位置范围内而且在时间范围内进行测量值的合理性检验。 Further, not only the test and the reasonable values ​​measured in the time range during each measurement position in the range. 为此,例如在密度范围内确定偏差的界限值,这些界限值不允许超过两个前后相接的或位置上相邻的邻接的值。 For this purpose, for example, determine the deviation in the density range of the limit value, the limit value does not allow more than two adjacent front and rear contact contiguous values ​​or positions. 在此,合理性测试是基于,在胶印方法中印刷装置在正常运行中只允许颜色值的持续变化,这样油墨密度的超过确定数量级的突变可立即归因于测量系统中的故障。 Here, reasonableness test is based on, an offset printing method in a printing apparatus only allows the continuous variation of color values ​​in normal operation, so that ink density exceeds a magnitude determined immediately due to mutation fault measurement system. 此外可设置一个显示装置,该显示装置通知关于印刷过程的状态的信息。 Further may be provided a display means, the display means notifies information about the status of the printing process. 如果测量系统没有检测到偏差或仅检测到很小的可容忍的偏差并且借助于机器控制装置调节,则在显示器上向印刷人员显示OK状态。 If the measurement system does not detect the deviation or detected only small deviations can be tolerated and by means of adjusting the machine control, the OK status is displayed on the display to the printing art. 如果机器没有处于这个稳定的状态中,则这在显示器上可识别并且印刷人员知道产生了废页。 If the machine is not in the steady state, this can be identified on the display and the printed page will appreciate that the waste produced.

该测量方法也可用于页张的间接的湿度测量。 This method can also be used for indirect measurement of the humidity measurement sheet. 为了测量湿度,润湿剂以通常方式被一直减少,直到在加网印刷中在页张上出现所谓的“起脏”。 To measure humidity, a wetting agent has been reduced in the usual manner, until the so-called "scumming" on the sheet in the screen printing. 该起脏根据经验首先在页张起始处、在侧面的页张边缘处以及在具有70%~90%面积覆盖率的网点块中显示出。 The scumming in the first sheet at the beginning, at the side edges of the sheets and in the halftone dot block having 70% to 90% of the area of ​​coverage showed empirically. 然后,湿度值又被以一个确定的固定的百分比值提高。 Then, the humidity value is fixed and a percentage value is determined increases. 对于在线测量,在页张上在印刷质量控制条中或在专门设置在页张上的位置上对于每种油墨在页张边缘处引入70%~90%网点块。 For online measurements, or for each of the inks introduced into the 70% to 90% dots in a block on the edge of the sheet in the sheet at the print control strip specially arranged on the position on the sheet. 由此,由对这个块的面积覆盖率及所印刷的油墨密度的了解可用测量头可靠地检测轻微的起脏。 Thus, the measuring head can be used by the understanding of the block and area coverage of the printed ink density reliably detect slight scumming. 由此可调节和监测油墨-水平衡。 Whereby adjustment and monitoring of the ink - water balance.

图1示出了一个单张纸轮转印刷机1,它具有一个续纸器模块2、一个收纸器模块3以及四个设置在该续纸器模块与该收纸器模块之间的印刷装置4、5。 Figure 1 shows a sheet-fed rotary printing press 1, having a feeder module 2, a delivery module 3, and four printing means between the feeder module and the delivery module is provided 4,5. 单张纸轮转印刷机1的该构型当然应仅仅理解为示例,因为续纸器2与收纸器3之间的印刷装置4、5的数量与本发明的实质无关。 Sheet-fed rotary printing press 1 of this configuration will of course be understood merely as an example, because the number of feeder 2 and the printing paper receiver means between 3 and 4, regardless of the spirit of the present invention. 印刷装置4、5通过传送滚筒9相互连接,由此,堆叠在续纸器2中的印刷页张705可被输送通过各个印刷装置4、5到收纸器3并且可在印刷装置4、5中被印刷。 4,5 printing apparatus interconnected via a transfer roller 9, whereby the feeder printed stacked on page 23 and the printing apparatus may be 705 sheets can be transported through the respective printing unit to the sheet receptacle 4,5 4,5 It is printed. 在页张行进方向上观察,最后的印刷装置5与其它印刷装置4的区别在于,该最后的印刷装置具有一个测量杆6,该测量杆作为扫描装置用于鉴定印刷好的页张的印刷质量。 Viewed in the direction of sheet travel, the last printing unit 5 differs from that of other printing apparatus 4, the last printing apparatus having a measuring rod 6, the measuring beam as a scanning means for identifying the printing quality of printed sheet . 测量杆6因此安置在最后的印刷装置5中,因为在这里所有在印刷过程中施加的油墨已经存在于印刷页张705上并且由此存在印刷页张的最终状态。 Thus the measuring beam 6 arranged in the last printing unit 5, where all of the ink as applied in the printing process is already present on the printed sheet 705 and thereby the presence of the final state of the printed sheet. 在此意义下,应更宽地理解印刷装置4、5这一概念,因为显然这些印刷装置4、5中的一个或多个也可以是上光装置、封缄装置或其它的处理页张的装置。 In this sense, it should be understood that a broader concept of 4,5 printing apparatus, the printing apparatus because obviously the one or more 4, 5 may be coating apparatus, or other sealed unit of processing sheets device. 即使所述其它装置在印刷机1中已存在,有意义的是,测量杆安装在最后的装置5中,以便可检查具有全部上光层的页张705。 Even if the other devices already present in the printer 1, expedient, the measuring beam is mounted at the end of the device 5, so that the page can be checked with all the glaze layer 705 sheets. 全部印刷装置4、5都具有一个压印滚筒7和一个橡皮布滚筒8,压印滚筒与橡皮布滚筒形成印刷装置4、5的印刷间隙100。 All the printing apparatus having an impression cylinder 4, 7 and 8 a blanket cylinder, the press nip of the printing apparatus 4, the blanket cylinder and the impression cylinder 100 is formed. 此外,每个印刷装置4、5装备有一个输墨装置13。 Moreover, each printing unit is equipped with a 4,5 inking unit 13 a. 滚筒7、8及输墨装置13支承在印刷机1的侧壁14中并且被那里的电动机和传动装置驱动。 7,8 roller and the inking unit 13 is supported and driven by a motor and gear there in the side wall 14 of the printing press.

在图1中的放大视图中可更清楚地看到印刷滚筒7、8之间的印刷间隙100。 In the enlarged view of FIG. 1 can be seen more clearly in the press nip between the printing cylinder 100 7,8. 此外,最后的印刷装置5中的印刷间隙100的周围连同测量杆6的放大视图还示出了测量杆6的横截面相对于印刷滚筒7、8的直径的大概的大小比例。 Further, around the press nip 5 last printing apparatus 100 together with an enlarged view of a measuring lever 6 also shows the approximate size of the cross section of the measuring beam proportional to the diameter of the printing cylinder 6, 7, 8. 在压印滚筒7上还安置有一些叼纸牙101,这些叼纸牙引导页张705绕着压印滚筒7、从传送滚筒9接收页张并且将页张传递给收纸器3。 7 are also on the impression cylinder there are arranged the grippers 101, the grippers 705 to guide sheets around the impression cylinder 7, the transfer roller 9 receives the transfer sheet and the sheet 3 to the sheet receptacle. 在通过测量杆6进行的测量过程期间,印刷好的页张705一方面在其后端部上被印刷间隙100抓持,另一方面在其前端部上被叼纸牙101抓持。 During the measurement process by the measuring beam 6, the printed sheet 705 on the one hand at its rear end portion 100 is caught hold press nip, on the other hand gripping the gripper 101 at its front portion. 由此保证:页张705在测量过程期间仅可最小程度地运动,这对于测量过程来说在这样的方面是有意义的,即,页张705与测量杆6之间的距离在测量期间应尽可能不变化。 This ensures that: the movable sheet 705 only minimally during the measuring operation, for which the measurement process is in this aspect is significant, i.e., the distance between the sheet 6 and the measuring beam 705 during the measurement should be does not change as much as possible. 测量杆6的横截面的尺寸在图1中对于印刷机1当页张规格为102cm时在该其端面上具有102mm的宽度及69mm的高度。 6 of the measuring beam cross section dimension in FIG. 1 for the printer 1 when the sheet having a width of 102cm specifications and 69mm 102mm in height of the end face thereof. 此外,测量杆6相对于水平线稍微倾斜,由此,当页张705被叼纸牙101及印刷间隙100引导时,该测量杆平行于该页张705的表面延伸。 Furthermore, the measuring beam 6 is slightly inclined relative to the horizontal, whereby, when the guide sheet 100 is 705 and the gripper 101 press nip, the measuring rod extends parallel to the surface 705 of the page sheets. 在测量杆6上固定着一个传感器15,但该传感器也可集成在测量杆6中。 6 is fixed on the rod with a measuring sensor 15, but may also be integrated in the sensor measuring beam 6. 该传感器15是一个光学传感器,例如是一个可识别页张705上的标记的摄像机。 The sensor 15 is an optical sensor, for example, an identification mark on the sheet 705 camera. 此外,传感器15还可用于观测外部光源800以及可用于触发通过测量杆6进行的测量过程。 Furthermore, the sensor 15 can be used for observing and measuring the external light source 800 can be used to trigger a process performed by the measuring beam 6. 为此,传感器15与印刷机1的测量电子电路单元201及计算机200联网。 For this purpose, the sensor 15 and presses the measurement electronic circuit unit 1 201 200 and computer networking. 因此,通过传感器15进行的测量过程可被这样控制,使得只有当没有外部光800照射在测量面上或直接照射到扫描装置6上时才测量。 Thus, by measurement sensor 15 may be controlled so that only when the external light is not irradiated onto the measuring surface 800 or directly to the scanning irradiation device 6 when measuring. 传感器15可由一个组合的传感器或由多个分开的传感器组成。 15 may be a sensor or combination of sensors separated by a plurality of sensors. 也可超过测量杆6的总长度地、分布地设置多个传感器15。 It may also be more than the total length of the measuring rod 6, a plurality of sensors 15 distributed. 这些传感器15在此也可集成在测量杆6中。 The sensors 15 may also be integrated in the measuring beam 6.

图2示出了一个单张纸轮转印刷机1,与图1不同,该单张纸轮转印刷机装备有一个页张翻转装置10,由此在双面印刷的情况下可在四个第一印刷装置4、5中印刷一个页张705的一个面,在四个第二印刷装置4、5中印刷另一个面。 Figure 2 shows a sheet-fed rotary printing press 1, and different from FIG. 1, the sheet-fed rotary printing machine provided with a sheet turning device 10, whereby in the case of duplex printing may first four 4, a printing apparatus printing a sheet surface 705, the other surface printed in the second printing unit 4, four. 出于这个原因,印刷机1在图2中具有两个印刷装置5,在这两个印刷装置上各安装一个测量杆6,因为无论是页张的正面还是该页张的背面必须各通过一个测量杆6检测。 For this reason, the printer 1 has two printing apparatus 2 in FIG. 5, in which two printing units 6 each mounted a measuring beam, because both the front sheet or the back sheet must page through each of a 6 detects the measuring beam. 为了在此也可鉴定印刷好的页张705不仅关于正面而且关于背面的最终状态,测量杆6位于翻转装置10前面的最后的印刷装置5中及收纸器3前面的最后的印刷装置5中。 To this can be identified not only printed on front sheet 705 and the final state on the back of the measuring beam 6 is located in front of the inverting device 10 the last printing unit 3, and 5 in front of the last printing sheet receptacle device 5 . 作为特点,单张纸印刷机1在图2中具有这样的可能性,即调换这些测量杆6。 As features, sheetfed 1 is a possibility in FIG. 2, i.e. exchange the measuring beam 6. 这就是说,测量杆6设计得易于取下并且也可安装在另一个印刷装置4中。 That is, the measuring beam 6 designed to be easy to remove and may also be mounted in the printing apparatus further 4. 图2中为此将一些连接装置安装在位于所述两个印刷装置5前面的印刷装置4上。 In Figure 2 some of the connecting means is mounted on that end located in front of the two printing apparatus printing apparatus 4 5. 被设计用于接收测量杆6的印刷装置5、4为此设置有一些电连接装置,这些电连接装置各连接在一个测量电子电路单元201上。 Measuring rod designed to receive the printing apparatus 6 is provided for this purpose 5,4- some of the electrical connection means, each of these electrical connection means connected to a measuring electronics unit 201. 在测量杆6插入到相应的印刷装置5、4中时,通过测量电子电路单元201的相应编码来自动地报告:测量杆6当前位于哪个印刷装置5、4中。 When the measuring beam 6 is inserted into the corresponding 5,4 printing apparatus, the report is automatically measured by the electronic circuit corresponding coding unit 201: measuring beam 6 which is currently located in the printing apparatus 5,4. 测量电子电路单元201又与印刷机1的控制台及计算机200相连接,由此可在那里使所有测量值显示给印刷机1的操作人员。 An electronic measuring circuit unit 201 and the printer 200 is connected to the console and computer 1, whereby all measured values ​​displayed to the operator where the printing press 1. 此外,在操作台200上还可改变印刷机1的调定值,以便控制印刷质量。 Further, the console 200 may be adjusted to change the setting of the printer 1, so as to control print quality. 此外,印刷机1的计算机200通过一个电缆连接的或无线的连接装置12、例如也通过互联网连接装置与印前阶段的一些装置11相连接,这些装置11尤其是用来制造胶版印刷机的印版的印版曝光机。 Furthermore, the computer 200 is connected to the printer 1 via a cable or wireless connection means 12, for example, the Internet connected via the connecting means of some devices prepress stage 11, these means 11 are used in particular for producing printed on offset printing press printing forme exposure machine. 通过到印前阶段11的连接12可使得源自测量杆6的测量的数据也可被用于改变印前阶段11中的制造过程。 By connecting to the pre-press stage 11 such that the data 12 may be derived from measuring rod 6 may also be used to change the manufacturing process of the prepress stage 11. 由此,可以使得在印刷过程中有比仅仅改变印刷机1的调定值可实现的改变更大程度的改变。 Thus, there can be made in the printing process than simply changing a greater degree of change of key presses a setting change can be achieved. 此外,可优化印版的制造。 In addition, to optimize the printing plate manufacturing. 在印刷机1的计算机200上还可连接有一个手动测量装置202,该手动测量装置可用于校准测量模块603的目的。 On the computer 200 may be connected to the printing press 1 has a manual measurement device 202, the measuring device may be used manually measuring module 603 for calibration purposes.

图3中描绘出了测量杆6的内部,其中,测量杆6被这样构造,使得该测量杆可固定在印刷装置5、4中,而在测量杆6的内部设置有一个可移动的测量车605。 Figure 3 depicts the internal measuring lever 6, wherein the measuring beam 6 is designed such that the measuring rod may be fixed to the printing means 5,4, and in measuring inner rod 6 is provided with a movable measuring carriage 605. 测量杆6在此延伸在印刷页张的整个宽度上,以便也可以可靠地检验印刷页张的边缘区域。 In this measuring beam 6 extends over the entire width of the printed sheet, so that inspection can be reliably printed sheet edge region. 测量车605为此可在测量杆6的内部移动,以便也可在页张的整个宽度上测量。 For this purpose the measuring carriage 605 can be moved inside the measuring rod 6, so that also can be measured over the entire width of the sheet. 为了检测印刷页张的表面,测量车605在图3中具有八个测量模块603,这些测量模块具有八个测量头622,其中,测量车605可以多步地或连续地移动,由此,在四色印刷中在测量16次之后,已跨越多个印刷页张705测量了总共32个墨区。 In order to detect the surface of the printed sheet, the measuring carriage 605 has eight measurement module 3603 in FIG., These measuring module 622 having eight measuring head, wherein the measuring carriage 605 may be a multi-step or continuously moved, whereby, in four-color printing after the measurement 16, has a plurality of printed sheet 705 spans a total of 32 measured inking zones. 为了该移动过程,测量车605支承在一个导轨606中,其中,该测量车被一个直线电动机604驱动。 For this movement, the measuring carriage 605 is supported on a rail 606, wherein the measuring carriage 604 driven by a linear motor. 为了使测量车605的维护简单,通过移去这些侧壁601可将该测量车从侧面从测量杆6中取下。 In order to maintain the measuring carriage 605 is simple, by removing the side walls 601 may be removed from the side surface of the measuring vehicle from the measuring beam 6. 为此,这些侧壁601被设计得易于拆下,这就是说,这些侧壁通过多个螺钉固定在测量杆6的壳体上。 To this end, the side walls 601 is designed to be readily removable, that is to say, the side walls by a plurality of screws in the housing 6 of the measuring beam.

测量杆6基本上由一个U形的型廓件构成,该U形的型廓件在朝着印刷页张的侧敞开。 Measuring beam 6 is constituted by a substantially U-shaped profile member, the U-shaped profile open towards the side member on the printed sheet. 为了避免脏物以及尤其是印刷油墨侵入,用一个可拆下的底板615封闭U形的型廓件的敞开侧,该底板附加地具有用玻璃制成的透明的部分616,由此,测量车605上的测量模块603可透过底板615的透明的部分616扫描位于其下方的承印物。 In order to avoid dirt and printing ink, especially invasion, with a detachable base plate 615 closed U-shaped profile member open side, the base plate additionally has a transparent portion 616 made of glass, whereby the measuring car measuring module 603 may be located on the substrate 605 below the scan through the transparent portion 616 of the bottom plate 615. 除了这些测量模块603和它们的电子电路单元之外,在测量车605上还存在其它装置。 In addition to these measurement modules 603 and their electronic circuit unit 605 on the measuring carriage there are other means. 因为测量模块603除了光谱测量头622之外还具有一些照明模块623,所以,测量车605一定设置有一个照明源610。 Since the measurement module 603 in addition to the spectrum measurement head 622 also has some of the lighting module 623, therefore, the measuring carriage 605 is provided with a certain illumination source 610. 该照明源是一个闪光灯610,该闪光灯由一个位于测量车上的电源装置612供给电能。 The illumination source is a flash lamp 610, located in the flashlight 612 consists of a power supply device supplying electric power measuring car. 该电源装置612又与测量模块603的电子电路单元通过柔性的电缆618与测量杆6的壳体相连接。 The power supply device 612 in turn connected to the electronic circuit unit measurement module housing 603 through the flexible cable 618 and the measuring beam 6. 这些柔性的电缆618的、固定在测量杆6的壳体上的端部终止在电插头连接装置619中,测量杆6借助于该电插头连接装置与印刷机1和测量电子电路单元201的供电装置相连接。 The flexible cable 618 is fixed to the end portion of the measuring lever 6 of the housing terminates in an electrical plug connection means 619, the measuring beam 6 by means of a power supply device and a printer unit 201 of the electronic circuit measuring the electrical plug connector devices are connected. 电能及信号传输的连接在此可借助于可插接的或可转动的组合插头来实现。 Connecting power and signal transmission can be realized by means of this pluggable combination connector or rotatable. 包括测量模块603在内的所有电部件都安装在一个或几个电路板631上,以便保证窄空间上的短的电流路径及信号路径。 All electrical components, including the module 603 comprises a measurement are installed on one or more circuit boards 631, in order to ensure short current path and a signal path on a narrow space.

因为在测量车605上只有一个闪光灯610,所以该闪光灯的闪光必须借助于一个耦合光学装置611及一些连接在该耦合光学装置上的光导体614传送给各个照明模块623。 Because in the measuring carriage 605 is only a flash 610, the strobe flash so must a means of coupling optics 611 and some of the light conductor is connected to the optical coupling device 614 is transmitted to each lighting module 623. 除了闪光灯610的电源装置612之外,为了提供必需的能量,在测量车605上还存在一些闪光电容器(Blitzkondensatoren)607。 The flash device 612 in addition to the power supply 610 outside, in order to provide the necessary energy, in the measuring carriage 605, there are some flash capacitor (Blitzkondensatoren) 607. 此外,测量车605还包括一个分配器装置620,用于将电能分配给各个电负载并且用于分配测量车605中彼此联网的部件的电信号。 Furthermore, the measuring carriage 605 further comprises a distributor means 620 for distributing power to various electrical loads and for measuring the electrical distribution network 605 to one another vehicle member. 但扫描装置6不仅能够光谱测量印刷页张的表面,而且它还用于检测套准标记以及用于分析这些套准标记。 However, the scanning device 6 can not only measure the spectrum of the surface of the printed sheet, and also for detecting register marks and means for analyzing the registration marks. 为此,测量车605具有一个右侧的套准传感器608及一个左侧的套准传感器613。 For this purpose, the measuring carriage 605 has a registration sensor 608 and a right side of a left side of the register sensor 613. 由此可检测印刷页张的边缘区域中的套准标记。 Whereby detection of the register mark edge region of the printed sheet. 也可设置另外的套准传感器,这样,每个测量模块603都具有一个套准传感器,以便可并行地跨越承印物705的整个宽度测量多个套准标记。 It may also be provided an additional register sensor, so that each measurement module 603 has a register sensor, so as to be in parallel across the entire width of the printing material 705 measuring a plurality of registration marks.

因为测量车605中的全部电子电路单元都安置在非常小的结构空间中,所以,测量车605的例如百分之七十的容积被部件填满,在相对小的空间中形成很多废热。 Because all of the electronic circuit unit of the measuring carriage 605 are disposed in a very small space, so that, for example, measuring the volume of the vehicle is filled seventy percent of the member 605, is formed a lot of waste heat in a relatively small space. 为了可将废热排出并且为了避免尤其是对测量模块603的损害及影响,测量杆6的内部被液体冷却。 In order to discharge waste heat and to avoid damage and in particular on the measurement module 603, the measuring beam 6 of the internally cooled liquid. 通过测量杆6的内部的及侧壁601中的多个通道621建立一个闭环的冷却循环回路,其中,该冷却循环回路通过侧壁601中的冷却剂通道617闭合。 Establishing a closed loop cooling circuit through the internal passages 6 and a plurality of sidewalls 601 measuring beam 621, wherein the cooling circuit is closed by the side wall 617 of the coolant passage 601. 冷却剂通道621、617由测量杆6的外侧上的冷却剂接头602供给以冷却剂。 621,617 coolant coolant passage 602 is supplied on the outside of the joint 6 to the coolant by the measuring rod. 因此,用于使冷却剂循环的泵不必安装在测量杆6本身的内部,而是可连接在外部。 Thus, a pump for circulating the coolant need not be installed inside the measuring beam 6 itself, but may be connected externally.

测量杆6的在图4中示出的侧视图除了示出测量杆6的基本上U形的型廓件之外还示出在U形的型廓件中延伸的冷却通道621,这些冷却通道在测量杆6的两个端面上通过侧壁601中的冷却剂通道617连接成闭环的循环回路。 4 in a side view shown in FIG. 6 except that the measuring beam is shown outside the measuring beam substantially U-shaped profile element 6 is shown a further cooling channel 621 extending in a U-shaped profile member, cooling channels the two end faces of the measuring beam 6 is connected to the closed loop circulation through the side wall 601 of the coolant passage 617. 此外可看到测量杆底板中的用玻璃制成的盖615,该盖保护测量车605上的敏感的测量模块603免受污染。 Further it can be seen that the cover plate 615 made of a measuring rod in the glass, the lid 603 on the sensitive measuring module measuring carriage 605 protected from contamination. 测量杆6的U形的壳体、侧壁601及具有其用玻璃制成的嵌入件616的测量杆底板615通过密封装置相互连接,由此,没有尘屑或液体能到达测量杆6的内部。 U-shaped housing of the measuring beam 6, having a sidewall 601 and an insert 616 which is made of glass plate 615 of the measuring rod is connected to each other by a sealing means, whereby there is no dust or liquid to reach the interior of the measuring rod 6 . 此外,在底板615的外侧上有一个排斥脏物的表面628,相对于测量杆的纵向延展方向横向的接片629在该表面上延伸。 In addition, there is a rejection of dirt 628 on the outside surface of the bottom plate 615 with respect to the longitudinal direction of the measuring rod extending transversely extending tabs 629 on the surface. 这些接片629将承印物705在其被测量时保持在一定距离上并且由此避免承印物705与底板615直接接触。 The tabs 629 holding the substrate 705 when it is measured over a certain distance and thus avoiding direct contact with the substrate 705 and the base plate 615. 接片629也可被涂层从而排斥脏物。 Tab 629 may also be coated to repel the dirt.

图5示出了从下面看测量杆6的视图,其中,在此可清楚地看到测量杆底板615。 FIG. 5 shows a view from below of the measuring beam 6, which can be clearly seen in this bottom plate 615 measuring rod. 测量车605具有八个测量模块603,这些测量模块各由真正的测量头623及照明模块623组成。 Measuring carriage 605 has eight measurement module 603, which each consist of a real measurement module measuring head 623 and illumination module 623 components. 为了可测量具有32个墨区的印刷页张的整个宽度,测量车605在每个测量过程之后朝侧面移过一个或多个测量块。 In order to measure the entire width of the printed sheet having the ink zone 32, the measuring carriage 605 move to the side through one or more blocks of measurements after each measurement. 因此,这些测量模块603之间的距离为四个墨区,由此,这些测量模块603并行地测量刚好各第四个墨区。 Thus, the distance between the measurement module 603 is four inking zones, whereby, the measurement module 603 to measure exactly parallel each fourth inking zone. 在四个扫描过程之后则跨越一种颜色的全部32个墨区测量了页张。 After four scan across all the areas 32 of one color ink sheet was measured. 如果用四种颜色来印刷,则相应需要16个扫描过程。 If four colors are printed, the corresponding process requires 16 scans. 此外,在图5中可看到一个可运动的遮挡器627,该遮挡器可遮盖一个测量模块603。 Further, in FIG. 5 can be seen a movable shutter 627, the shutter 603 can cover a measurement module. 该遮挡器627可设置在每个模块603上并且被电地或机械地驱动,但也可将一个共用的遮挡器627用于所有模块603。 The shutter 627 may be provided and electrically or mechanically driven on each module 603, but may be a common shutter 627 603 for all modules. 该遮挡器627在图5中可在页张传送方向上横向于测量杆6移动并且保护测量模块603的光学装置以免在测量过程之间的损坏,遮挡器也可在各个测量过程之间遮盖测量杆6的整个底侧。 The shutter 627 in FIG. 5 transversely to the sheet transport direction on the measuring lever 6 is moved and protect the optical measuring module 603 in order to avoid damage to the apparatus between the process measurement, the shutter cover can also be measured between each measurement the entire bottom side of the rod 6. 为此,遮挡器627的驱动装置与印刷机的计算机200相耦合。 For this purpose, the driving means of the printing press of the shutter 627 coupled to a computer 200.

在图5中,在一个端侧601上设置或者也在两个端侧上各设置有一个校准面801,该校准面可由位于外部的测量模块603行驶到。 In FIG. 5, is provided at one end or side 601 are each provided with an alignment surface 801 on both end sides, the surface can be measured by the calibration module 603 is located outside the travel. 如果一个测量模块603定位在校准面801上,则它的标准化的表面被测量。 If a measurement module 603 is positioned on the calibration surface 801, it normalized surface is measured. 该表面是白色的瓷砖(Kachel),该瓷砖与页张的白色一致。 The surface is white tile (Kachel), which is consistent with a sheet of white tiles. 通过测量瓷砖801可随时在承印物705上的两次测量之间校准测量模块603。 It may be at any time between the two calibration measurements on a substrate 705 of module 603 measured by measuring tile 801. 不可行驶到瓷砖801的测量模块603通过相邻的测量模块603的转移校准来校准。 Not with the measurement module 603 of tile 801 is calibrated by transferring the calibration measurement module 603 adjacent. 为了保护瓷砖801免受污染,该瓷砖也可借助于一个可侧向移动的盖802来封闭。 Tile 801 in order to protect from contamination, the tiles may be laterally movable by means of a lid 802 is closed. 由此,瓷砖801在校准测量之间总是保持被盖802遮盖。 Accordingly, calibration measurements tile 801 is always maintained between the cover 802 is covered.

而且在图5中可看到排斥脏物并且将页张保持一定距离上的接片(Stege)629。 And can be seen in FIG. 5 and the sheet repel dirt holding tab (Stege) 629 over a distance. 这些接片629与测量杆6的盖615相连接。 Measuring the tabs 629 and the cover 615 is connected to the rod 6. 测量杆通过一个位于盖615下方的玻璃层616密封。 Measuring rod positioned beneath the cover 615 by a layer 616 of a sealing glass. 为了清洁玻璃层616,带有接片629及多个用于测量模块603自由地观察页张705的空缺部的盖615被设计得可翻转开或可取下,由此可容易地整面清洁玻璃层616。 In order to clean the glass layer 616 with a tab 629 and a plurality of measurement modules 603 for freely observing the cover sheet 615 vacant portion 705 is designed to be reversible or removable to open, whereby the entire surface may be easily cleaned glass layer 616.

除了在图3中描述的具有设置在测量车605上的光源610的可能性之外,也可根据图6中的设置将闪光灯610安装在测量车605之外,甚至安装在测量杆6之外。 In addition to the possibility of having a light source 610 disposed on the measuring carriage 605 is described in FIG. 3, may be provided according to FIG. 6 in flash 610 installed outside the measuring carriage 605, and even mounted outside the measuring beam 6 . 在此情况下,必须使用柔性的光导体614,这些柔性的光导体使测量杆6的不可运动的部件与测量车605相连接。 In this case, you must use a flexible light guide 614, such that the flexible light conductor 6 immovable measuring rod member 605 is connected to the measuring carriage. 但是这些柔性的光导体614也可在灯610如图3中那样位于车605上的情况下使用。 However, such flexible optical waveguides 614 may be a lamp 610 in FIG. 3 as positioned on the case where the vehicle 605 use. 在此情况下,这些光导体614可如图6那样分开地通到每个测量模块603,但这些光导体614也可在一个部位上被聚成束并且经过测量车605内部的较长的路径通到对应的测量模块603。 In this case, the light guide 614 may be separately passed to 6 as each measurement module 603, but the light guide 614 may also be bundled in a polymerization site and the longer path through the interior of the measuring carriage 605 in FIG. through the corresponding measurement module 603. 如果所有测量模块603获得唯一一个光源610的光,则保证所有测量模块603在测量时使用相同的光并且因此测量条件对于所有模块603都相同。 If all the measurement module 603 to obtain a unique light source 610, the measurement module 603 to ensure that all use the same light when the measurement and thus measurement conditions are the same for all modules 603. 也可将一个附加的光导体614连接到灯610上,该附加的光导体在另一端上通到一个光参考测量头632中。 Also an additional light guide 614 may be connected to the lamp 610, the additional light conductor through a reference optical measurement head 632 at the other end. 该光参考测量头632具有这样的任务:测量灯610的光并且在变化时输出一个用于维护及检查的信号。 The reference light measuring head 632 has the task of: measuring light 610 and outputs a signal when a change in maintenance and inspection. 由此及时地识别故障的或由老化引起地不再具备足够的发光强度的灯610。 Thereby identifying the fault in a timely manner due to aging or to no longer have sufficient light emission intensity of the lamp 610.

作为图6中的柔性的光导体614的替换方案,也可如图7a及图7b中所示使用光学的长度可调节的波导节(Posaune)的原理。 As an alternative to a flexible light guide 614 in FIG. 6, using the principle of adjusting the length of the optical waveguide section may be as shown in Figure 7b (Posaune) and also in FIG. 7a. 在此情况下,测量车605及测量杆6的光导体分别在它们的端面625、626上终止,由此,它们总是刚好对准地位于对面。 In this case, the measuring carriage 605 and the measurement light conductor 6 bars, respectively on their end faces 625 and 626 is terminated, whereby they are always situated opposite exactly aligned. 在测量车605的光导体的端面626与测量杆6的端面625之间存在一个光学的中间空间624,该中间空间如图7a及图7b中所示与测量车605的位置相关地大小是不同的。 An intermediate space is present between the optical end faces of the measuring rod 626 and the carriage 605 of the measuring light conductor end surface 6256 of 624, and 7a and 7b, the position of the measuring carriage 605 as shown in FIG size of the intermediate space in relation to different of. 这些光导体之间的该光学的中间空间624可通过该中间空间被镜面化而被跨接。 The intermediate space between the optical light guide 624 may be mirrored to be bridged by the intermediate space. 借助于这种反射镜可使从测量杆6的光导体射出的光束在测量车605处于任意位置中时耦合到该测量车的光导体中。 By virtue of this mirror allows the light guide 6 from the measuring beam emitted beam measuring carriage 605 is in the optical conductor is coupled to the measuring vehicle in any position. 这样一种光学的长度可调节的波导节比柔性的光导体614不易磨损,考虑到百万次的测量过程,这是极其重要的。 Such an optical waveguide of a length-adjustable section easy to wear than the flexible optical waveguides 614, taking into account the measurement process millions of times, which is extremely important. 因为已经证实:柔性的光导体614在相对少的测量过程之后就易于断裂,从而必须更换。 As has been demonstrated: a flexible light guide 614 after a relatively few measurement process is easily broken, and thus must be replaced.

图8a及图8b从下面观察地各示出了测量杆6,具有测量头622及照明模块623的两种不同的布置。 FIG. 8a and FIG. 8b be observed from below each show an arrangement of two different measuring beam 6, a measurement head 622 and illumination module 623. 在根据图8a的布置中,这些测量头622及这些照明模块623彼此相交叉地定位,使得由承印物反射的光不被直接位于对面的测量头622扫描到,而是十字方式地交叉。 In accordance with the arrangement of Figure 8a, the measuring head 622 and the lighting modules 623 are positioned to intersect each other, so that the light reflected by the substrate is not located directly opposite the measuring head 622 to scan, but the cross-cross manner. 这种配置允许在窄空间上布置多个测量头,因为测量头622与位于对面的照明模块623之间的距离在图8a中相对于根据图8b的布置可更小,在根据图8b的布置中,这些测量头622扫描刚好位于对面的照明模块623所反射的光。 This configuration allows a plurality of measuring heads are arranged in a narrow space, because the distance between the measuring head 622 of the lighting module 623 located opposite in phase in respect to FIG. 8a can be smaller in accordance with the arrangement of Figure 8b, in the arrangement of Figure 8b , the measurement heads 622 scan 623 is located just opposite the light reflected by the illumination module. 图8a中的更小的结构空间由对角的交叉产生,因为照明模块623与所属的测量头622之间的距离不能被任意地减小。 Less space in Figure 8a generated by crossing diagonal, since the distance between the illumination module 623 and measurement head 622 belongs can not be arbitrarily reduced. 该距离通过从照明模块623到承印物再返回到测量头622的光路来确定。 The distance from the back by lighting module 623 to the substrate 622 to the optical path of the measurement is determined. 通过该交叉解决方案可使测量杆6或测量车605的宽度减小。 The solution can cross through the measuring beam 6 or measuring the width of the vehicle 605 is reduced. 因为在印刷装置4、5的印刷间隙100附近的位置情况变窄的情况下,位置需求是决定性的标准,所以根据图8a的布置更好地适合该情况。 Because in the case where the position 100 close to the printing apparatus 4, the press nip is narrowed, the space requirement is decisive criterion, it is better suited for the case of the arrangement according to FIG. 8a.

图9中示出了印刷页张705上的印刷质量控制条700。 FIG 9 shows the print quality of the printed sheet 705 on control rod 700. 印刷质量控制条700如同真正的印刷图像那样在印刷机1的印刷装置4、5中被印刷在页张705上。 As the print control strip 700 as a real printed image is printed on the sheet 705 in the printing device 4, the printing press 1. 在经过最后的印刷装置5之后,页张705和印刷质量控制条700被印完并且可被测量杆6测量。 After the last printing unit 5, the sheet 705 and the print control strip 700 is complete and may be printed on the measuring beam 6 measurements. 页张705在此具有所谓的中等规格即74cm的页张宽度并且具有23个墨区701,703。 The sheet 705 having a so-called medium size i.e. 74cm sheet having a width of 23 and ink zones 701, 703. 每个墨区701,703由6个颜色测量块702及四个其它的测量块704组成。 Region 701, 703 of each ink color measured six block 702 and block 704 four other measuring composition. 这些墨区701,703被测量杆6的这些测量模块603测量。 These regions 701, 703 are measured these inks measurement module 603 of the measuring beam 6. 通常在一个页张705上通过一个测量模块603仅测量每个分色及墨区701,703的一个测量块702,704。 Typically on a sheet 705 by a measuring module 603 only measures each measurement area and the ink color separation block 701, 703, 702, 704. 在23个墨区701,703及六个测量模块603以及每个墨区10个测量块702,704的情况下,在所有测量块701,703被检测一次之前,在40个印刷页张705上有40个测量过程。 In the case of 23 six ink zones 701, 703 and 603 and the measuring module 10 measurements for each inking zone of the blocks 702, 704, 701, 703 until all the measurement block is detected once in the printed sheet 40 705 40 measurement process. 对于几个页张上的多个测量必须设置多个测量模块603。 For a plurality of measurements on several measurement modules sheet 603 must be set. 另外,在一个页张上也可设置多个印刷质量控制条700,例如页张起始处一个,页张中间一个,页张末端一个。 Further, the sheet may also be provided a plurality of print control strip 700, for example at the beginning of a sheet, a middle sheet, a sheet end. 作为替换方案,在继续印刷工作期间,即当印刷机1以生产速度运转并且全部测量块702,704已达到了它们的期望状态时,这些测量模块603也可定位在包含关于多种或所有颜色的颜色信息的一些专门的测量块702,704上方。 As an alternative, during the continuing printing operation, i.e., when the printing press 1 and all operated at production speed measurement block 702 have reached their desired state, the measurement module 603 may also include or be positioned on a variety of all colors Some specialized measuring color information block 702 above. 这些测量模块603则必须或者完全不或者及其少有地移动,因为在此这些颜色信息在一个测量块中局部地紧实地存在。 The measurement module 603 or not and must either be moved entirely rare, since here the color information is present locally in a compact measurement field block. 在这些专色的测量块内发生变化时,则该测量方式又被改变,并且所有测量块702,704如在开始阶段中那样又被测量。 When a change occurs in the spot color blocks these measurements, the measurement method has been changed, and all the measurement block 702, as has been measured in the starting stage.

图10示出了与图5类似的实施形式,在两个实施形式中,可侧向移动的测量车605位于一个被罩起来的封闭的测量杆6中。 FIG 10 shows a form of embodiment similar to FIG. 5, in both embodiments, the laterally movable measuring carriage 605 housed together in a closed measuring beam 6. 但在图10中测量杆具有一个连贯的玻璃盖634,该玻璃盖封闭测量杆6的下侧。 However, the measuring beam having a coherent glass cover 634 in FIG. 10, the lower side of the cover glass 6 is closed measuring rod. 在测量杆6的外侧上,在该连贯的玻璃盖634上还具有一个用于引导页张633的页张导板,该页张导板在纵向方向上带有两个缝槽639。 6 on the outside of the measuring beam, the consistency of the cover glass 634 also has a sheet guide for guiding the sheet 633, this page sheet guide plate 639 having two slots in longitudinal direction. 透过这些缝槽639及玻璃盖634,在测量车605中的由测量头622及照明模块623组成的测量模块603可测量在页张导引装置633下面经过的承印物705。 Through these slots 639 and the glass cover 634, measured by the measuring head module 622 and illumination module 623 consisting of the measuring carriage 605 in the sheet guide 603 may measure device 633 through the substrate 705 below. 附加地,在玻璃盖634上及在这些缝槽639的内部设置的接片629位于外部。 Additionally, in the glass cover 634 and disposed within slots 639 of the tabs 629 located outside. 这些接片629防止承印物705接触并且由此污染玻璃盖634。 These tabs 629 prevent the substrate 705 in contact with the cover 634 and thereby contaminate the glass. 因为接片629如图10中所画出的在此情况下可处于测量模块603的光路中,因为测量车605必须跨越承印物的整个宽度测量,所以应设置一个补偿装置,该补偿装置补偿这些接片629在测量模块603的光路中的影响。 Because the tab 629 drawn in Figure 10 in this case may be in the optical path of the measurement module 603, since the measuring carriage 605 must be measured across the entire width of the substrate, it should be provided a compensation device, the compensation device to compensate for these webs 629 measure the effects of the optical module 603 in the path. 这样的补偿装置在本申请的其它地方已经描述。 Such a compensating device has been described elsewhere in this disclosure.

图11示出了对图10替换的实施形式。 FIG 11 shows an alternative form 10 of FIG. 而且在此一个可移动的测量车605位于一个测量杆6中,但该测量杆向下敞开,因此测量车605被一个底板635封闭。 Also in this a movable measuring carriage 605 is located in a measuring rod 6, but the measuring rod is open downwardly, and therefore the measurement vehicle 605 is a bottom plate 635 closed. 测量车605为此具有一个用板材制成的底板635,该底板附加地设置有一些装有玻璃的透视口636。 For this purpose the measuring carriage 605 having a base 635 with a sheet metal, the base plate is additionally provided with a number of perspective port 636 with glass. 这些玻璃口636刚好定位在这些测量模块603的光路下面。 These glass port 636 positioned just below the optical path of the measuring module 603. 因此在图11中在测量车605上具有8个测量模块603的情况下在8个测量头622及8个照明模块623下面设置刚好16个用玻璃制成的透视口636。 8 thus has eight measuring heads 622 and 623 arranged below the lighting module 16 is just the case of oral perspective 8 measurements 603 made of glass modules 636 in the measuring carriage 605 in FIG. 11. 这些用玻璃制成的口636可如图11中那样构造成圆形的,但它们也可设计椭圆形的、矩形的或其它形状的。 The port 636 may be made of glass as in Figure 11 is configured in a circular, but they may be designed oval, rectangular or other shapes. 除了装有玻璃的透视口636之外,在测量车605的底板635中还具有一些小的鼓风通道637,鼓风可通过这些鼓风通道从测量车605的内部逸出。 In addition to port 636 with a perspective view of a glass, the base plate 635 in the measuring carriage 605 also has a number of small blowing passage 637, the blower may escape from the interior of the measuring carriage 605 through which ventilating ducts. 该鼓风用于使承印物705相对于底板635保持距离,以便避免页张705的接触并且由此避免污染用玻璃制成的口636。 The blower 705 for the substrate holder 635 relative to the base distance to avoid contact of the sheets 705 and port 636 thereby avoiding contamination made of glass. 同时,借助于测量车605的内部的通过鼓风产生的过压来避免外部物体从外部侵入到测量车605的内部。 At the same time, by measuring the internal overpressure of the vehicle 605 generated by the blower to prevent foreign objects from entering the inside to the outside of the measuring carriage 605. 鼓风通道637借助于测量车605内部的鼓风源638例如一个小的压缩机或风扇被加载鼓风。 Blast passage 637 inside the measuring carriage 605 by means of the blast source 638, for example, a small compressor or fan blower is loaded.

图12a、12b、12c及12d示出了在单张纸轮转印刷机1中通过测量杆6进行测量过程期间承印物705的不同的固定可能性。 FIG. 12a, 12b, 12c and 12d illustrate different possibilities of fixing the sheet-fed rotary printing press 1 through the printing material during the measurement process the measuring beam 6 705. 除了图12a中的由图1公开的可能性之外,即承印物705在其一个端部上借助于页张传送叼纸牙101并且在其另一个端部上通过压印滚筒7与橡皮布滚筒8之间的印刷间隙100被固定地抓持,还得到其它即使当页张705不处于印刷间隙100中时使该页张固定的可能性。 In addition to the possibility of FIG. 1 disclosed in FIG. 12a, i.e., the transfer substrate sheet 705 and a gripper 101 at its other end by means of the blanket impression cylinder 7 at its one end the gap between the printing cylinder 8 is fixed grip 100, also obtained even when other fixing possibilities sheets page when the printed sheet 705 is not in the gap 100. 根据图12b,页张705在两个端部上由多个传送叼纸牙101保持在一个传送滚筒9上并且因此在测量期间固定在测量杆6下面。 FIG 12b, the sheet 705 on both end portions of a plurality of transfer grippers held on a transfer drum 9 and thus the measuring rod 6 is fixed below 101 during the measurement. 取代至少所述在页张传送方向上在后面的传送叼纸牙101,也可如图12c中那样将一个鼓风装置16安装在传送滚筒9上方,该鼓风装置将页张705的自由的没有固定在叼纸牙中的端部压在并且因此固定在传送滚筒9上。 Substituted on at least the sheet conveying direction behind the conveying gripper 101, shown in FIG. 12c may be as a blowing means 16 is mounted above the conveyor rollers 9, the sheet consisting of the blower 705 an end portion not fixed to the grippers and thus of pressure in the cylinder 9 is fixed to the transfer. 此外,也可使用根据图12d的解决方案。 Further, the solution may also be used in accordance with FIG. 12d. 在该解决方案中,页张705基本上借助于负压固定在传送滚筒9上。 In this solution, the sheet 705 is substantially fixed by means of a negative pressure in the conveying roller 9. 为此,滚筒9在与页张705接触的表面上具有多个空气孔18,这些空气孔与滚筒9内部中的一个真空腔17形成连接。 To this end, the drum 9 having a plurality of air holes 18 on the surface in contact with the sheet 705, the air holes inside the drum 9 is connected to a vacuum chamber 17 is formed. 负压因此将页张705固定在该滚筒上,这附加地还可通过一个传送叼纸牙101支持,但并非必须。 The suction sheet 705 thus fixed to the drum, which may additionally support 101 by a transfer gripper, but not necessarily. 真空腔17可以是滚筒9内部中的一个抽吸泵的组成部分或者连接在滚筒9之外的一个抽吸泵上。 The vacuum chamber 17 may be an integral part of the interior of the drum a suction pump 9, or a suction pump connected to the outside of the drum 9.

图13示出了如何进行测量杆6在印刷机1的一个印刷装置中的装配。 Figure 13 shows how the measuring beam 6 mounted in a printing apparatus in a printing press. 在印刷机1中的安装位置的俯视图中可看到,测量杆6原则上相对于页张传送方向19横向地装入在印刷机1的侧壁14之间。 Can be seen in the plan view of the mounting position in the printer 1, the measuring principle of the lever 6 with respect to the conveying direction of the sheet 19 loaded transversely between the side walls 14 of the printing press. 因为测量杆6即使在已经存在的机器中也应该是可后装备的,所以装配通过两个侧面的装配板20进行,所述装配板原则上可安装在任何印刷机1中,只要有所需的位置。 Since the measuring beam 6 even in existing machines should also be equipped with the so assembled by assembling two lateral panels 20, the assembly can be installed on any printing press 1 in the plate in principle, as long as the desired s position. 这些装配板20也可补偿侧壁14之间的不同的距离,其方式是这些装配板被构造得有不同的厚度。 The mounting plate 20 may also compensate for different distances between the side walls 14, a manner that the mounting plate is so constructed as to have different thickness. 装配板20借助于装配螺钉21固定在侧壁14上并且承载用于测量杆6的支承装置。 20 by means of a mounting plate mounting screws 21 and fixed to the sidewall 14 supporting the carrier means 6 for the measuring beam. 测量杆6在其两个端部上各具有盖22,这些盖包围测量杆6并且承载轴承23。 Each measuring beam 6 has a cover 22 at its two ends, the cover 6 encloses the measuring beam 23 and carries bearings. 这些轴承23将测量杆6相对于装配板20支撑并且降低印刷机1会传递给测量杆6的振动。 The bearings 23 supporting the measuring beam 6 with respect to the mounting plate 20 and is passed to a press to reduce vibration measuring lever 6. 这些盖22可被这样地设计,使得测量杆6可简单地从盖22上取下。 The cover 22 may be designed in such a way that the measuring beam 6 can be easily removed from the cover 22.
